Catalase is a kind of liquid enzyme preparation fermented by
Aspergillus Niger; it can effectively catalyze hydrogen peroxide
and decompose hydrogen peroxide into oxygen and water. And catalase
only reacts with hydrogen peroxide.

low energy and water consumption requirements are increasingly used
in pre-treatment processes for bleach clean up to hydrolyse
residual peroxide before dyeing

Product Advantages:

1. Water saving: only one cold rinsing is required2. Time saving: reduce rinsing time, the bleach clean up only need
10-20 min3. Energy saving: reduce processing time and no need to heating4. Safe dyeing: hydrogen peroxide can be completely broke down

Product Application:

1. Drain the spent bleaching liquor2. Fill with fresh cold water to obtain a liquor ratio suitable for
dyeing3. Check that pH is in the range 5-10 (6-7 is most suitable) and
temp. is 20-60 centi.4. Add 0.1-0.2g/l diluted formulations and start circulation5. Check after 10-20min treatment6. Continue with dyeing in the same bath

Notes:1. When the density of H2O2 is higher than 1000PPM, the enzyme CANNOT work well.2. The activity of enzyme will be the best at 50℃, but it is NOT
recommended to dye directly if treated at 50℃.3. After treated for 10~20min, you can use the MDRCK test paper to
test the density of residual H2O2.
